Tides are the rise and fall of the oceans. They are caused by the gravity, or pull, of the Moon and Sun. The Moon's gravity is the main force in causing tides. It makes the oceans bulge out toward it. Another bulge occurs on the opposite side, because Earth is being pulled toward the Moon and away from the water. The water on the side farthest away from the Moon is least affected by its gravity.
Answer is: 15675 J.
m (H₂O) = 75g - mass.
ΔT (H₂O)<span> = 75</span>°C - 25°C = 50°C -<span> change in temperature.</span>
C (H₂O) = 4,18 J/g·°C - <span>specific heat of water.
</span>Q = m·C·<span>ΔT.
Q- heat (in Joules-J).
</span>Q = 75g · 50°C · 4,18 J/g·°C = 15675J = 15,675 kJ.

Answer:
Forest Fire
Explanation:
Forest fire is an ecological factor over which biological processes like seed dispersal and their germination is dependent upon. Some plants germinate under high temperature underground regions of the soil which is covered by the hot soil affected by the burning by the forest fire. Some of the coniferous trees like longpole pines have hard cone which exhibit the seeds. These cones exhibit the serotonin resins which are melted by the forests fire hence fire helps in dispersal of the seeds. Other plants like Eucalyptus and Banksia are also dependent upon fire for seed dispersal.
